Wayne's experience (see below) reminds me that I am still searching for the adapter Suntour made that converts the top mounted symetric shifters to stops for bar end shifters. I just haven't had the time to custom make one. One of my Centurion Pro Tours has this Suntour branded adapter but I would like to find another for my other Pro Tour. Anyone have one they could part with?
Steve Willis? You often have the odd part sought after.
Thanks.

Besides the top-mount boss pictured on the link, there are at least two
(maybe more, but I know of at least two) types of braze-on mounts for top-mounted shifters. I think these were designed specifically for top-mount shifter assemblies like the Suntour Symetric and others. They (the braze-ons) consist of a single, threaded semi-cylindrical boss. My '83 3Rensho is so equipped, and it came outfitted with a Dura Ace top-mount shifter assembly (I hadn't seen one of those before either), part of the first (7400?) 6sp indexed DA group. I wanted to outfit the frame with Suntour components. While the Suntour Symetric system fit the boss, I wanted to use conventional Superbe Pro shifters. After finally scrounging up one of the little adaptors Steve mentions above, I found that it would not fit the braze-on. The braze-on was too long longitudinally for the adapter. I had to file down the fore and aft edges of the braze-on, ultimately making it sort-of a square with rounded corners, before the adaptor would fit. It wasn't terribly difficult, and the adaptor now fits, but the adaptor was definitely made for a different braze-on than the one on the 3Rensho.
So when you are hunting for these bits, just be aware that one size does not fit all.
